NASHUA – A Merrimack family’s second run-in with the law within four months has landed 25-year-old Trevor Dinneen in jail, while his mother, Marian Dinneen, is scheduled for arraignment next month on allegations she attacked police officers during the scuffle.

While Marian Dinneen, 52, was booked and later released on personal recognizance bail after the Sunday afternoon incident, police said son Trevor was transported to Valley Street jail after he refused the services of a bail commissioner.

Superior Court Judge Charles Temple on Tuesday ordered Trevor Dinneen to continue to be held in jail on preventive detention, adopting Assistant County Attorney Brett Harpster’s recommendation, which Harpster said was based on the fact Dinneen was out on bail on a previous arrest at the time of Sunday’s incident, and he also had “time hanging over his head,” meaning he was in the process of serving a suspended sentence.

After Sunday’s incident, Merrimack police ended up charging Trevor Dinneen with one count of criminal threatening, a Class B felony; and seven Class A misdemeanors, including four counts of simple assault on a police officer, and one count each of resisting arrest or detention, criminal mischief, and domestic violence – simple assault.

Marian Dinneen was charged with three counts of simple assault on a police officer, and one count of resisting arrest or detention, all Class A misdemeanors.

Attorney Amanda Armillay, a public defender who represented Trevor Dinneen at Monday’s bail hearing, asked that her client be released on personal recognizance bail “so he can continue getting the treatment he needs.”

Armillay referred to treatment for mental health and substance use disorder, issues that she said are likely “the underlying issue” in his alleged behavior.

But Harpster said that while the charges “are obviously allegations at this point,” Trevor Dinneen is accused of being violent toward police officers when he allegedly resisted arrest, kicked two officers and struck them with his knee.

“He was out on bail on violent charges, and now he’s accused of violent acts,” Harpster said.

The bail Harpster referred to stems from an incident in early June that led to Dinneen’s arrest on two felony counts of reckless conduct and one misdemeanor offense of theft of a motor vehicle.

Police said at the time that officers called to the Dinneens’ Old Blood Road home for a report of a woman possibly struck by a vehicle were met with “uncooperative witnesses” as they tried to determine what, if anything, took place.

The woman, who turned out to be Marian Dinneen, denied being struck by a car, police said in their reports.

But a neighbor went to police the next day, bringing them a video storage card from his home’s video security system – which he said was recording at the time of the alleged incident.

Upon reviewing the video, police said they saw a BMW back out of the Dinneens’ driveway as a man tried to grab onto it. Police said it appeared the man was being dragged by the vehicle as it backed into the street.

At that point, the video shows a woman in the street with her hands up in an apparent attempt to get the driver to stop. Instead, the driver allegedly kept going and the car struck the woman, knocking her down, and barely missing her legs as the driver took off.

Police said they identified the driver as Trevor Dinneen, and issued a warrant for his arrest.

He was eventually taken into custody, booked on the charges and released on $5,000 personal recognizance bail.

A grand jury, late last week indicted Dinneen on two felony reckless conduct charges, accusing him of placing the man and woman “in danger of serious bodily injury.”

As for the incident that allegedly unfolded Sunday, police said officers initially responded to the Dinneen residence “to check the welfare of an individual” after the department “received a report of a possible domestic assault involving a knife.”

Officers first encountered Trevor Dinneen, but as they tried to speak with him, he allegedly attempted to go back inside the house “to avoid being detained.”

When the officers tried to detain him, police said, Marian Dinneen appeared and allegedly “attempted to grab one of the officers … to prevent (the officer) from detaining Trevor.”

Police said a struggle ensued, during which both suspects allegedly “violently resisted” the officers’ attempts to bring the situation under control.

They said Marian Dinneen allegedly kicked one officer twice, and was allegedly “resisting so violently” that an officer had to deploy a Taser to subdue her.

Once the two were in custody, police said, officers began investigating the matter they were initially called to, and learned that Trevor Dinneen, earlier in the evening, allegedly threatened another man with a knife, then allegedly “used the knife to cause damage to a vehicle,” police said.

He was also accused of assaulting a household member by punching him or her in the face, they said.

Marian Dinneen, following booking, was released on personal recognizance bail, police said. She is scheduled to appear in Merrimack district court on Oct. 17.
